General f-harmonic morphisms

Arab Journal of Mathematical Sciences, 2016
In this paper, we prove that a map between Riemannian manifolds is an f-harmonic morphism in a general sense if and only if it is horizontally weakly conformal, satisfying some conditions, and we investigate the properties of f-harmonic morphism in a ...

Foams in contact with solid boundaries: equilibrium conditions and conformal invariance

, 2005
A liquid foam in contact with a solid surface forms a two-dimensional foam on the surface. We derive the equilibrium equations for this 2D foam when the solid surface is curved and smooth, generalising the standard case of flat Hele Shaw cells.

The Fractional Carleson Measures on the Unit Ball of ℝn+1

Journal of Function Spaces and Applications, 2013
We construct a quantity in terms of Lp integral of the Jacobian of a conformal self-map on the unit ball of ℝn+1. Then, we characterize the fractional Carleson measures on the unit ball by the quantity.

Optimization Of Conformal Cartographic Projections For The Slovak Republic According To Chebyshev’s Theorem

Slovak Journal of Civil Engineering, 2015
Disadvantages of the currently used Křovák’s map projection in the Slovak Republic, such as large scale distortion, became evident after the division of Czechoslovakia.

A New Mathematical Basis of Google Maps

Kartografija i Geoinformacije, 2019
In the middle of 1990s, Google made available world maps which can be zoomed in to the largest scales, with the maps collectively named Google Maps. Google Maps is primarily intended to facilitate navigation by car, public transport, bicycle, airplane or

1/2 BPS Wilson loops in non-conformal N $$ \mathcal{N} $$ = 2 gauge theories and localization: a three-loop analysis

Journal of High Energy Physics
We study the 1/2 BPS circular Wilson loop in four-dimensional SU(N) N $$ \mathcal{N} $$ = 2 SYM theories with massless hypermultiplets and non-vanishing β-function.

Secant Cylinders Are Evil—A Case Study on the Standard Lines of the Universal Transverse Mercator and Universal Polar Stereographic Projections

ISPRS International Journal of Geo-Information
The literature usually calls downscaled versions of basic conformal map projections “secant”, referring to conceptual developable map surfaces that intersect the reference frame.

Analytical Solution for Finding the Second Zero of the Ahlfors Map for an Annulus Region

Journal of Mathematics, 2019
The Ahlfors map is a conformal mapping function that maps a multiply connected region onto a unit disk. It can be written in terms of the Szegö kernel and the Garabedian kernel. In general, a zero of the Ahlfors map can be freely prescribed in a multiply

Scattering by an Almost Circular Cylinder With Smooth Surface [PDF]

Journal of Electrical and Electronics Engineering, 2008
The problem of finding the scattered and diffractedfields of a plane wave by an infinite cylinder witharbitrary cross section presents considerabledifficulty. We discuss a boundary perturbationmethod in which we conformally map the givenarbitrary surface

Quantum chaos in Liouville CFT

Journal of High Energy Physics
Fast scrambling is a distinctive feature of quantum gravity, which by means of holography is closely tied to the behaviour of large-c conformal field theories.
